For a project like this, I'm not sure that 'boring' is a bad thing. There's a link to documentation and relatively little fluff. In my game development repo's, I have an image, because it's reasonable to judge a game by it's visuals.

If diagrams (like those produced by draw.io) could be used to better communicate how incubator-age functions and why it is important, you could use them, but I don't think you need to.

An explanation of repo architecture could be useful for people wanting to hack on it. [1]

Edit: Just noticed the Documentation section doesn't link to the website. If I'm getting started with your project, the getting started documentation on your website will be far more useful to me than a very long PDF.
